A footrest is a piece of furniture designed to support the feet while sitting. It helps improve comfort and posture by allowing the legs to rest at a more natural angle. Footrests can be adjustable or fixed in height and are commonly used with chairs, especially in office settings. Footrests are often made from various materials, including wood, plastic, or fabric. They can also come with features like non-slip surfaces or massage functions. Using a footrest can reduce strain on the lower back and legs, making it a useful accessory for those who spend long hours sitting, such as office workers or students.
